We need something similar to FIPS for interoperable software and standards. Organizations will fall in line when money is at stake.

Say for example your local/state/federal agency publishes (or accepts) documents exclusively in ods/odf instead of proprietary formats, that will automatically drive adoption of software and prevent lock-in.

Agressive interoperability at the protpcol and exchange format - its why email mostly works even forcing Google to back off when they tried to change email to be rendered by their cdn (i forget the name of the offering - but was similar to what news pages were being pushed for speedup). Bad actors will always abound - like Microsoft spiking the documnt standards by pushing through ooxml when odt/odf was gaining traction. Or basically just coercing the decision makers like in Berlin(?) where they moved their offices into hte city to get them to drop Linux/Openoffice.
